Hubble takes us to within a stone's throw of the big bang itself," said Massimo Stiavelli of the Space Telescope Science Institute (STScI) in Baltimore, and the HUDF project lead.
Opinion mike, not reality.
Personally i will take some convincing that everything in existence, every atom, just sprang into existence in a blinding flash in a split second.
Those atoms existed, somewhere.
Where did it all come from mike ?.
We still dont know
Looking back to the dawn of time
Only a century ago, the origin of the Universe was a topic where reliable experimental data was lacking.
The situation is quite different now. Cosmology, the science that aims to explain how the Universe formed and evolves, has since grown into one of the richest and hottest fields of experimental research.
Key discoveries made during the last eight decades show that in the past the Universe was far denser and hotter than it is today, and that it started to cool and expand — a process that is still going on today — about 13 700 million years ago. This version of events, known as the Big Bang theory, is currently the most accepted scenario. But the picture is still far from complete. Questions such as what triggered the birth of the Universe, or how it will evolve in the future, remain unanswered.

But we do know it exists.
The case for the Big Bang
Planck will measure the fluctuations of the CMB with an accuracy set by fundamental astrophysical limits.
In the 1920s, astronomers discovered that the Universe hasn’t always existed as we see it today. It is in fact continuously expanding. This means that all the matter and energy that it contains was packed into a much smaller and hotter region in the past. This was the first piece of evidence for the Big Bang theory of the formation of the Universe.
Later, scientists learnt that stars are the 'factories' that make most chemical elements in the Universe, including oxygen, carbon and iron. But certain elements must come from elsewhere — those few elements were produced in the earliest epochs of the Universe, when it was still very hot.
These findings formed the basis for the Big Bang theory, but it gained wide scientific support only when the next clue was discovered. In 1964, two researchers accidentally detected radiation coming from all directions in the sky, a uniform glow pervading the Universe. This radiation is the relic of the Big Bang itself.
These three clues supported the theory that the Universe has always been expanding, so there must have been an initial period during which all existing matter and radiation were tightly coupled together in a high-temperature mixture.
With time the Universe cooled down, and at some point it must have reached a temperature low enough for the radiation to be decoupled from matter. Light would then have travelled freely throughout the Universe for the first time. That 'first light' should still be detectable today, and it was, in fact, the glow detected in 1964.
This relic radiation from the Big Bang is called the Cosmic Microwave Background (CMB). It is an important piece of evidence for the Big Bang theory which has not been studied to its full potential.

We dont know everything, but we know a lot. But not knowing everything isnt the same as knowing nothing
But this is distracting us from the point being debated, that is reality being independant of observation.
So back to the question big bang (the generally accepted theory) or not, did the universe exist one hour after
